Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8460, here are decompositions:

13 + 8447 = 8460
17 + 8443 = 8460
29 + 8431 = 8460
31 + 8429 = 8460
37 + 8423 = 8460
41 + 8419 = 8460
71 + 8389 = 8460
73 + 8387 = 8460

Showing the first eight; more decompositions exist.
